The bidding for free agent reliever Darren O'Day is heating up and could see a resolution soon.

Dan Connolly of the Baltimore Sun reports that the Nationals are considered the front-runners for O’Day and that he could make a decision before the Winter Meetings begin on Monday. The Orioles are still hoping to retain him while the Braves are also in the mix. The Dodgers are no longer in the running, though this could be about geographic preference more than anything else, as O’Day’s wife, Elizabeth Prann, is a television anchor based out of Washington, D.C. This looks like a Beltway Battle for his services.

O’Day is at the top of the class in a weak market for free agent relievers. The 33-year-old sidearmer owns a 2.07 ERA dating back to 2009, including a 1.92 ERA over the past four seasons. He’s said to be looking for a four-year contract in excess of $30 million. Odds are he’ll get it.
